Based on a synthesis of the literature, a model for problem posing cognitive processes was formulated, and validated. The major constructs incorporated in this framework were the situations in which problem posing occurs. For each situation, four cognitive processes were established: the editing of problems based on iconic or symbolic stimuli, the filtering of important and critical information, the comprehending of the structural relations in quantitative information, and the translating on the quantitative information from one mode to another. The data suggested that all four cognitive processes contributed to problem posing abilities with the filtering and editing having a heavier role than the comprehending and translating processes.
